KRT80

Keratin 80 (KRT80) is a type of keratin protein that is encoded by the KRT80 gene in humans. Keratins are a family of fibrous structural proteins that are key components of the cytoskeleton of epithelial cells. They provide mechanical support and play a crucial role in the protection and integrity of epithelial tissues.

Function

KRT80 is primarily expressed in the hair follicle and is involved in the formation of the hair shaft. It is a type II keratin, which typically pairs with type I keratins to form intermediate filaments. These filaments are essential for the structural integrity and resilience of hair fibers.

Clinical Significance

Mutations in the KRT80 gene have been associated with certain hair disorders, including monilethrix, a condition characterized by beaded or fragile hair. Understanding the role of KRT80 in hair biology can provide insights into the mechanisms underlying these conditions and potentially lead to targeted therapies.
